Hirschmann switches
Belden has expanded its Hirschmann product offering to include IP67-rated switches in the company's Octopus range of networking devices.
The switches provide eight twisted pair (100 Base-TX) as well as two fibre optic uplink (1000Base-FX) ports and comprehensive management functions.
The twisted pair ports are designed as four-pin M12-D connectors.
The fibre optic uplinks are available in Profinet or Ethernet/IP versions to ISO/IEC 61076-3-106 Variant 1 or Variant 4, respectively.
The IP67 switches support fast redundancy techniques and various security mechanisms.
Functions that can be managed per SNMP v1, v2 and v3 or Telnet include redundancy mechanisms such as Rapid Spanning Tree and Hiper Ring, the latter for access control to IEEE 802.1x, as well as filtering options per port, Flow Control with prioritisation and Traffic Shaping.
The entire configuration can be saved on site by means of an auto-configuration adapter and an interface also meeting the requirements of IP67 protection class.
In this way, the devices can be exchanged, if required.
For reasons of redundancy, the switches can be powered by two independent 24V DC or 36V DC supply units.
The switches of the Octopus range, which is complemented by an unmanaged five-port device, are designed for an operating temperature range of -40C to +70C.
They also meet the high EMC requirements in trains and vehicles and bear up to the mechanical loads in these environments.
The devices are also in line with the European standard for railway equipment applications (EN 50155).
